An electrical conductor is a material that can carry electricity.
A material that does not conduct (or allow the 'passage' of) electricity is called an "insulator".

Every material conducts electricity, some materials are just better than others. The best conducter of electricity is silver, but silver is very expensive. Because of this, copper is used as it is a very good conductor of electricity but it is cheap.
This is called a conductor.
It comes from the Greek word "electron." However, to the Greeks that word didn't mean what it does to us; it meant the material we call amber. It's called that because one of the first noticed electrical phenomena was that if you rubbed a piece of amber with a cloth you could build up a static charge and make a small spark.

An insulator.
If you know what the material is you can determine whether the material is a normal conductor of electricity by reference. If not try completing a circuit with torch battery(ies), a bulb from the torch, some wire and see if the bulb lights up. If so the material in the circuit conducts electricity.

Copper cables are reputed to carry electricity well.
For a material to conduct electricity, it must have free movable electric charges, such as free electrons or free ions, in order to 'carry' electricity. In the case of metals, there is a 'sea' of delocalized electrons. These free electrons can 'carry' the electricity, and thus, it is a conductor.

Insulator materials will not carry or conduct electricity.
It means that it's a material whose outer shell electrons move freely across the surface of the material. Conductors can carry an electric current
